Common questions
How is a KPERS pension calculated?
KPERS 1 and KPERS 2 use a formula: final average salary × multiplier × years of service. The multiplier is 1.85% (KPERS 1 service before 2014 earns 1.75%). KPERS's example: $40,000 × 1.85% × 30 years = $22,200 a year. KPERS 3 is a cash balance plan: your account balances are divided by an annuity factor.
When can I retire from KPERS?
KPERS 1: Full benefits at age 65 with 1 year of service; age 62 with 10 years; or any age when your age plus years of service equal 85 points. KPERS 1 only. KPERS 2 and 3: Full benefits at age 65 with 5 years of credited service, or age 60 with 30 years. Every tier can retire early, with a reduced benefit, at 55 with 10 years.
Does KPERS give a cost-of-living increase?
KPERS retirees don't receive regular COLAs; any increase needs a new law. KPERS 3 members can choose a self-funded 1% or 2% COLA at retirement, paid for with a lower starting benefit.
Is this the official KPERS calculator?
No. This is an unofficial estimate built from KPERS's published guides. It is not affiliated with KPERS. Your KPERS online account has the official benefit calculator, and KPERS decides your benefit.
